Privacy Policy

Last updated: May 8, 2026

Gym Bud ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information when you use the Gym Bud web application at gymbud.mknxgn.dev (the "Service").

1. Information We Collect

Gym Bud is designed to work entirely in your browser. We collect and store the following:

Workout data — exercise selections, weights, reps, sets, and session history. This data is stored locally in your browser's localStorage and is never transmitted to our servers.
Co-op session data — if you use the Co-op feature, a temporary peer-to-peer connection is established directly between your device and your partner's device using WebRTC. We do not store, log, or have access to any data exchanged during a co-op session.

2. Information We Do Not Collect

We do not collect, store, or transmit:

Your name, email address, or any personal identifiers
Account credentials (there is no account system)
Location data
Device identifiers or advertising IDs
Payment information

3. Local Storage

Gym Bud uses your browser's localStorage to save your workout history, preferences, and session state. This data is stored only on your device and is not accessible to us. You can clear this data at any time by clearing your browser's site data for this domain.

4. Co-op Feature & Third-Party Services

The Co-op workout feature uses PeerJS to establish a direct peer-to-peer connection between two devices. PeerJS uses a signaling server to initiate connections. While no workout content passes through their servers, your IP address may be visible to PeerJS signaling infrastructure during connection setup. Please review PeerJS's privacy policy for details.

5. Cookies

Gym Bud does not use cookies for tracking or advertising purposes. Standard browser storage ( localStorage ) is used solely to persist your workout data between sessions.

6. Children's Privacy

Gym Bud is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us so we can address it.

7. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Continued use of the Service after changes are posted constitutes your acceptance of the updated policy.
